After shaping generations of partygoers, this legendary event celebrates its 20th anniversary with an XXL edition—the biggest, most immersive, and most spectacular in its history.

For two decades, Megalloween has transformed Halloween into a truly unforgettable experience: a night where celebration meets horror, where haunted sets come to life, terrifying creatures emerge from the shadows, and thousands of people gather for far more than just a costume party.

Megalloween is all about a one-of-a-kind atmosphere: spectacular costumes, a packed dancefloor, cinematic horror-inspired productions, and an energy unlike anything else. Around every corner, expect a chilling surprise, a terrifying encounter, or a memory you’ll never forget.

For this 2026 edition, Festival du Soir is raising the bar once again. For one night only, a dedicated stage will be transformed into a cursed realm entirely devoted to the world of Halloween.

Twenty years deserves a celebration. But at Megalloween, we celebrate in the dark.

Prepare your costumes. Prepare your screams. Get ready to experience the most monstrous Halloween night of the year.

🎭 Costume mandatory.
